Answer:
in total 5 hours
Using proportions part/whole, percent/100 you put the 40 in the percent spot and the 2 in the part spot cross multiply and divide so 2 x 100 divided by 40 and you get 5
A Domain is the lowest and highest x value (-5,-2) is how it is formatted this means -5 to -2
Range is the lowest to highest Y value so (-3,3)
(-5,-2) - domain
(-3,3) - range
B Intercept are when the line crosses the acis labeled x so
(-2,0) and (2,0)
C F(1) means what is x when y is equal to 1 so we must estimate this
(-1,1) and (1.5,1)
D f(x) = -3 is when y is -3 so we look at the graph to see
-5 and 4 are the values for x
E f(x) < 0 means when y is above the x axis
This is between the x values of -2 and 2 or (-2,2)
